Something must have changed in bash. The code in refractasnapshot to remove old package list directories from the work directory stopped working, so if you've set save_work to "yes" then the old package lists don't get deleted.
At line 457 of refractasnapshot and line 586 of refractasnapshot-gui, change:
- Code:
if [[ -d "$work_dir"/iso/"$dir_prefix"* ]] ; then
rm -r "$work_dir"/iso/"$dir_prefix"*
fi
to:
- Code:
for dir in "$work_dir"/iso/"$dir_prefix"* ; do
rm -r "$dir"
done
